Build issue - go configuration?

I am trying to build and install free5gc for the first time. I’m following the stage-1-all-in-one instructions.

The two points that seem salient are the go packages {mux, http2, unix} appear to have installed properly. With that said, I’m getting errors during the build process that look like an improper go.mod file. I can’t post the build output… Does anyone know how to properly generate the file?

Thank you,
Anthony

I think I made it past this error. The fix was to make a go.mod file that looks like this:
module free5gc

go 1.16

require (
[mux depend] v1.8.0 // indirect
[http2 depend] v0.0.0-20210726213435-c6fcb2dbf985 // indirect
unix depend] v0.0.0-20210630005230-0f9fa26af87c // indirect
)

It might be helpful to add the steps to make the file in the setup docs.
